[ltp] Two external screens with native display

[G. Vincent Castellano]

I am working with the series of Thinkpads compatible with "IBM Mini 2504 Docking 
Station" (T60, T61, and Z61m) and want to be able to drive two external monitors 
along with the native display for a total of three independent screens.  I have 
tried with Linux Mint 16 and the "Displays" utility will recognize that I have 
three displays but will not enable more than two at a time.

I can provide the details of that crash if anyone here can help, but I am also 
willing to try another distribution if it is known to work better with more than 
two screens.
